How often does one political party dominate Texas politics?

Living in a state with a political majority can often skew the state politicians heavily in one direction, but just how influential can ideological majorities be?

According to data from Ballotpedia and Truth in Accounting’s State Data Lab, Texas has experienced a republican “trifecta” 11 times between between 1992 and 2013--far more than the national average rate of 5 times. Ballotpedia identifies a 'trifecta' when one major party holds the governorship, has a majority in the state senate, and a majority in the state house. Though the south is notorious for its republican leanings, few of Texas’ neighboring states reported GOP trifectas, and those who did only reported a small handful of occurrences. Arkansas and New Mexico reported none, while Oklahoma and Louisiana reported only three each.
However, simply because these states did not report many GOP trifectas is not to say that such political majorities never occur. When looking at democratic trifecta occurrences, Arkansas and New Mexico reported 11 each from 1992-2014. Louisiana reported eight, followed by Oklahoma with five and Texas with three. Despite these states’ residents traditionally voting heavily Republican in past presidential elections, democratic trifectas are far more common, showing a possible disconnect between the states’ residents and their governments.
